` APPAnATUs ron STM/:PING Leen-PAPER The Schedule referred to in these Letters Patent and making part of the same.

yTo all/whom it coacem': Y x ,Be it known that I, ALBERT RoHnBncK, of the cityof New York, in thecounty and State of New York, hay@` invented -a new and improved Machine. for Stamping Lace-Paper; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being. `had to `the accompanying drawing, forming part of this specification, in whichi Figure lfrepresents a vertical section of my improved lace-paper stamping--machine, taken on the plane of the line x-x, g. 2.

Figure 2 is a front elevation of the saine.

Figure f3is an inverted plan View, partly in section, of the same. l mi .Similarletters of reference indicate corresponding parts. y Y l This invention relates to a'new machine for stamping the perforated lace-paper used by confectioners, cigarm akers, and others. r

x Such paper has heretofore been perforated by a steel cutting-tool, which was struck. by hand, to cut'at once through anumber of sheets, it requiring many strokes of the hammer before the'whole cutting-face of the tool was made-to act.

The invention consists in.` providing certain machinery for dropping a hammer upon the-cuttingplate, so that quickeraction, with greater accuracyand neatness, can beproduced. v l

A composition-hammer, A, made of a soft metal,

`is fastened to a sliding plate, B, which works between l two vertical guide-plates G 0,!that are stationary, attached to avsuitable frame. The edges of the plate B are V-shaped, and lit into corresponding grooves in the plates O, as shown inY gA socket, A, is formed on the lower end of the'plate B, to receive the shank of the hammenwhich can beA fastened in the socket by a small slet-screw, b. V.

Upon then plates C O is supported a vertical cylin- ,der,"E, with perforated-upper and lower ends.

Through itis fitted a bar, F, that projects` from the plate B.

Around the bar F is (directly above the lower end `of the cyliuderE) fitted a perforated plate, c, which forms the lower support for two volute springsy G G, that are-arranged within the cylinder, around the bar F, as shown. l l

A perforated plate, d, is fitted loosely around the bar F, directly'below the upper head of the cylinder.

The plates c and d have inwardly-projecting Bauges e e, which retain the larger ends of the springs, as shown, to prevent the same from being caught between the edges of said plates and the cylinder.

When the plate B is raised, the plate c will compress the springs into a very short upper part ofthe cylinder, and Athese springs will force the plate and hammer down with great force upon the steel cuttingplate.

The plate B has a vertical slot, with a horizontal crook inthe middle, as shown in ytig. 2.

K is a horizontal shaft, having ,its bearingsv in the I plates C, behind -the plates B, and carrying two flni gers, f and g, that fit through the slot ofthe plate B.

When the shaft H is'rotated by suitable mechanism, in the direction of the arrow 1, the finger f'will iirst fit against the upper end of the. slot-'in B, and will raise the said plate and hammer onehalf its stroke. The finger g then catches under the middle shoulder It of the slot, and raises therebyfthe hammer, as far as required. `When the end of the finger q leaves the shoulder h, the plate is released, and the springs expand, to throw the hammer down with great force.

The plates crd are perforated, to allow the air to` escape while they are being moved togethenor apart.

When the hammer is worn, its shank can bem re- Vleased from the socket a, by letting the plate B work up and down without striking anything. )t will then readily throw off the remaining portion .of the hammer.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. A machine for stamping-lace-paper, consisting of the hammer A, slotted` plate B, driving-shaft H, cylinder-E, and springs G G, all arranged, combined, and loperating substantially as herein shown and described.

2. The plate B, having the bent slot, when coml bined wth'the shaft H, which has the fingers' f and y all arranged and bperating substantially as herein shown and described. t I l 3. The perforated plate' c, formed on the bar F below the springs G, in combination with the perforated plate d, which is loose on the ,bar F, above the springs G, both said plates having anges e, substantiallyvas vand for'the purpose herein shown and described.-

ALBERT ROHRBEOK.
